AUTOMATIC SEAL-CLOSURE non BOXES.

Specification of Letters Patent. Patented A 24 1920 Application filed February 7, 1920. Serial No. 357,037.

To all whom it may concern:

Be it known that I, JOHN A. WAOHTER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Automatic Seal-Closures for Boxes, of which the following is a specification.

This invention relates to boxes and particularly those usedfor displaying articles such as fire extinguishers which it is desired to, for practical purposes, lock or seal in the box without the use of mechanical keys or latches.

The object of the invention is to provide a box of this class in which, until the device is finally installed in permanent position where it is to remain, the contents of the box are readily accessible for examination, installation, etc, but in which when finally desired the contents may be so sealed in the box that it can only be opened by breaking some part of the box as for instance, the glass.

The invention consists in a novel form of locking plate which when inserted in one position renders the inclosure readily re lower portion of Fig. 2 showing the looking movable and which when inserted in a re verse position automatically locks itself, thereby in turn permanently locking the inelosure inside the box.

The invention consists furtherin many details of constructions which will be hereafter more fully set forth in the specification and claims.

Referring to the drawings in which like numerals represent the same parts throughout the several views Figure 1 is a face view of a box illustrating this invention in which the bottom slide or looking plate is locked in position,

Fig. 2 is a sectional view taken on the line 22 of Fig. 1.

Fig. 3 is a plan view taken on the line 3-3 of Fig. 1.. v

Fig. 4 is a changed position View of the plate in initial or shipping position.

The box shown in the drawings happens to be one for inclosing a fire extinguisher 10. It comprises the usual top 19., rear wall 1.4:, sidewalls 16 of any suitable material, prefcrably metal and is detachablysecured into the wall of the room by anysuitable means as for instance, the screw 18. The top and side walls heretofore described are provided with inwardly turned flanges 20 and 29.,

forming tracks within which the front glass 2% is detachably inserted from the bottom to move vertically. The box is provided with a permanent bottom 26 rigidly attached to the rear wall 14 and the sidewalls 16 by any suitable means such as soldering. This plate 26 is provided with a front flange 28 adapted to position and guide glass24 heretofore referred to. This permanent bottom member 26 is provided with a perforation, preferably a circular one, 30 located at a convenient point, as at its approximate center. This bottom member 26 is preferably made ofyielding material such as tin, which permits the bottom member to spring up and down slightly at its center.

Below the bottom member 26 heretofore described the side members 16 are provided with inwardly turned flanges 32 forming a horizontal trackway for a supplemental bottom locking plate 3% provided at its front edge with a combined locking flange and handle 36, adapted to act as a front support or lock for the edge of the glass 24 when the parts are in the position of Figs. 1 and 2 and to act as a handle when the parts are in the position of Fig. 4. So positioned on this plate 34- as to register with perforation 30 heretofore described is "formed a mound, knob or pin 38 of such a size that when the parts are in the position of Fig. 2 it springs up into perforation 30 and thus prevents ready removal of glass 24 which must be removed to give access to fire extinguisher 10.

On the other hand when thelocking plate 34 is in the position of Fig. 4, member 38 does not lock in perforation 30, consequently member 34 may be inserted and withdrawn at the will of the operator. The mechanism is used in this position when the box is being assembled and shipped to the place where it is finally used for retainin and displaying the fire extinguisher 10. Vhen, however, the box has been put on the wall through the agency of the screw 18 and the fire extinguisher has been put in place therein where it is expected to remain permanently except in case of fire, the operator after putting'in the glass 24 inserts plate 34 in the position shown in Figs. 1, .2 and 3, whereupon the knob 38 springs into the recess 80 thus permanently locking the glass 24 in the expected manner in case of of fire, to remove the extinguisher 10.

Having thus described my invention What I claim as new and desire to secure by Letment, and concealed means automatically operating independently of the closure at the termination of the locking movement of the plate to secure the latter against removal. V V

2. A 'box open at one side, a removable frangible closure for the open side, a looking plate slidably engaged with the box to secure the closure against opening movement, and concealed means permanently at tached to the box and automatically interlooking with the plate at the termination of the locking, movement of the'latter to V secure the plate against removal.

3. A box open at one side, a removable frangible closure for the open side, a locking' plate slidably engaged with the box to secure the closure against opening movement, and concealed means effective to automatically operate independently of the closure at the termination of the locking movement of the plate to secure the latter against removal when said plate is in one 7 of the box in place, and an interfitting pin and recess connection between said plate and end Wall adapted When the plate is placed With one side out to lock the plate to the end Wall and Which does not so lock it when the plate is reversed. r

In Witness whereof I have hereunto sub scribed my name in the presence .of't vo Witnesses.
